Management of Placental Abruption at 31 Weeks with Hypotension and Ongoing Bleeding
Immediate blood transfusion with massive transfusion protocol activation followed by emergency cesarean section is the most appropriate management for this patient. 1, 2
Immediate Resuscitation Priority
The presence of hypotension with ongoing bleeding indicates severe placental abruption (Grade III) with significant maternal compromise requiring urgent intervention 3, 2:
- Activate massive transfusion protocol immediately - transfuse packed red blood cells, fresh frozen plasma, and platelets in a 1:1:1 ratio to restore circulating volume and prevent disseminated intravascular coagulopathy 1, 2
- Hypotension is the first guide to the level of blood loss and indicates severe hemorrhage requiring aggressive volume resuscitation 4
- Delay in correction of hypovolemia is an avoidable factor in maternal deaths from hemorrhage 4
Delivery Approach
Proceed to emergency cesarean section after initiating resuscitation 3, 2:
- With a live fetus at 31 weeks and maternal compromise (hypotension), cesarean delivery is indicated when maternal or fetal status is not reassuring 5, 3
- The goal is rapid delivery once resuscitation has begun, as prolonging the abruption-delivery interval worsens maternal prognosis 6
- Vaginal delivery is reserved for cases of fetal demise, which is not the scenario here 5, 3
Why Not Corticosteroids Alone?
While corticosteroids for fetal lung maturation would normally be appropriate at 31 weeks, this patient's hemodynamic instability makes delaying delivery for steroid administration dangerous 2:
- Corticosteroids require 24-48 hours for optimal effect, which is not feasible with ongoing hemorrhage and hypotension 2
- Maternal stabilization and delivery take precedence over fetal lung maturation when the mother is hypotensive 3, 4
- The risk of maternal death from hemorrhagic shock and DIC outweighs the benefits of waiting for steroid effect 4, 2
Critical Intraoperative Considerations
During cesarean delivery, maintain aggressive hemorrhage management 1, 2:
- Continue 1:1:1 transfusion ratio throughout surgery 1
- Monitor fibrinogen levels closely - levels <200 mg/dL are associated with severe postpartum hemorrhage 1
- Consider tranexamic acid 1g IV to reduce blood loss, though evidence is strongest when given within 3 hours of birth 1
- Maintain maternal temperature >36°C as clotting factors function poorly at lower temperatures 1
Monitoring for Coagulopathy
Severe abruption with fetal compromise carries significant risk of disseminated intravascular coagulopathy 3, 6:
- Obtain baseline platelet count, PT, PTT, and fibrinogen levels immediately 1, 2
- Overt coagulopathy is ominous and indicates Grade IIIB abruption 6
- Transfuse cryoprecipitate if fibrinogen <100 mg/dL, though pregnancy targets should be >200 mg/dL 1
Common Pitfalls to Avoid
- Do not delay delivery to administer corticosteroids when the mother is hemodynamically unstable 3, 2
- Do not attempt conservative management with ongoing bleeding and hypotension - this is not a candidate for expectant management 5, 2
- Do not underestimate blood loss - the degree of hypotension guides resuscitation needs 4
- Do not wait for coagulation studies before initiating massive transfusion protocol in the setting of severe hemorrhage 1, 2
